sleeving cable size

Is 1/4" sleeving to big for most cable in a PC? I ordered 25' of 1/4" sleeving and was woundering if It would look nicer using 1/8" sleeving insted?

I used 1/4" for my built-in USB and for my power and light switches and fans I used 1/8".

For the USB cabling I needed 3/8" heat-shrink an I used 1/4" lights and fans.
I sleeved my fans, lights, USB, and buttons.

If it is techflex the 1/4" should be just fine. PSU will be bigger of course much bigger since the plugs are big.

What do you plan on sleeving?

I'm thinking I will just sleeve the wires in pairs (2 wires per sleeve) I'll sleeve the molex wires, Sata's, Fans', everthing i can fit into the 1/4" sleeving. I'll use electrical tape and tape the 2 wires togrther every 3" or so. That way they will stay in a line when sleeving.

The molex cables may be tight for the 1/4" I had problems with the USB mobo plug on the 1/4".
